UNITED STATES PATENT OFFICE.

OLE PEDERSON, OF JOLIET, ILLINOIS.

CASTER.

SPECIFICATION forming part of Letters Patent No. 223,948, dated January 2'7, 1880.

`M Application filed September 30, 1879. l

To all whom it may concern:

Be it known that I, OLE PEDERSON, of Joliet, Illinois, have invented a new and useful Improvement in Furniture Casters, of which the following is a clear, full, and exact description, reference being had to the accompan ying drawings, making a part of this speciiication, in which Figure 1 is a perspective view of'a caster with my improvements attached. Fig. 2 is a vertical section of same. Figs. 3 and 4. show details to be referred to.

The object of my invention is to produce a furniture-caster which will better stand the strain which they have to bear, and which is at the same time simple in construction 5 and it consists of the coubination of' devices hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe ihe exact manner in which I have carried it out.

In the drawings, A represents the shank of a caster, terminating at its bottom in the tlat plate a, and near its top provided with the groove c', for purposes hereinafter explained. On eachside of the dat plate a, is cast a short trunnion or axle, B, internally screw-threaded and countersunk for the purpose of receiving the screws b, which holdvthewheels b in position.

Around the shank Ais the sleeve G, formed in two halves longitudinally, for a purpose which will hereinafter appear, and provided with a ange, c, at the lower edge. and with a slot or opening, d d', on each side, near its upper edge, to receive the lugs d d, formed on Athe head of the screw D, as shown in Fig. 2. By means ofthe screw D the caster is readily secured within the hole prepared Jlior its reception in the leg of any article of furniture.

Within the sleeve C are cast the lugs c on opposite sides, which fit snugly into the groove a' in the upper part ot' the shank, and secure the shank in its position within the sleeve C, as shown in Fig. 2. On each half ot' the sleeve I provide the longitudinal grooves e for the reception of the lugs e e on the annular plate E, which, fitting around the sleeve, holds the two halves iirmly together, as shown in Fig. 1. The plate E not only forms a neat finish and ample protection to the lower end of the leg, but by means of the notches ff it acts as the head of the screw to receive a suitable wrench or screw-driver and operate the screw D. p

Instead ot' screw-threading the short trunnions B for the reception of the screws b, I usually make the trunnlons with a swell at the end to secure the wheels, as shownin Fig. 4. 'Ihis swell may be made either during the casting or by subsequent riveting. This construction obviates the use of screws.

Having thus explained my invent-ion, what l claim to be new, and desire to secure by Letters Patent, is i The shank A and sleeve C, provided with the notches ff and slots d' d', in combination with the screw D, formed with the lugs d, d, substantially as and for the purpose set forth.

OLE PEDERSON.
